To all whom it may concern: more openings for the passage of pins orscrews :0, into a Be it known that I, CHARLES NEWTON, a citizen ofgroove in the collar U, loose on the axle, which collar is the UnitedStates, residing at Torrington, in the county adjacent to another collarV, fitting against a shoulder y of Litchfield, State of Connecticut,have invented cer- 011 the inner periphery of the movable clutch member,5 tain new and useful Improvements in Automatic and having a pin Zpassing through a slot in the axle, Coaster and Brake Hubs, of which thefollowing is a de-- and engaging a sliding bar or red W, which passesinto scription, reference being had to the accompanying the hollow axle,by manipulation of which rod, the movdrawing and to the letters andfigures of reference able member may be shifted to throw one or theother marked thereon. of the speeds into or out of operation. 10 Myinvention relates to improvements in two speed Thus far the partsdescribed are similar to those doand automatic coaster and brake hub ofthe type illusscribed and illustrated in the above entitledapplicatrated in the applications filed by Fred E.
